RE: arrows
Arrow length, figure draw length plus an inch for broadhead clearance. My draw length is 29". My arrows are 30". Generally arrow weight will depend on the bow poundage. You want to shoot an arrow that will stabilize quickly at your bow poundage and draw length. Moststores will have a chart which will give you an indication of the weight arrow trhat will work at your draw length. As far as broadhead or point weight. That's generally a preference. They can vary from 100 to 180 grains. I think 125 grainswould be a reasonable average weight.
